|About the stats|
Over the course of his career, Willie Mitchell pitched 1,632 innings and made 598 plate appearances. Mitchell was worth 14.3 Wins Above Replacement (17.1 as a pitcher and -3.0 as a hitter) and -1.2 Wins Above Average (1.9 as a pitcher and -3.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 14.3 WAR becomes 15.0 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the -1.2 WAA becomes 6.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mitchell 27.4 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Willie Mitchell has a Hall Rating of 26, leaving him nowhere close to induction to the Hall of Stats.
